IMPROVED ATOMIZING TUBE.

TO 'ALL WHOM IT MAY CQNCRN:

Be it known that I, C. H. ECOLESTON, of Oxford in the county of Chenango, and State of New York, have invented an improvement in tomizing Tubes; and Ido hereby declare that the following, taken in connection with the drawings which accompany and form part of this speciication, is a description of my invention sulicient to enable those skilled in the art topractise it.

In the use of atomizing tubes, (the general construction and mode of operation of which for producing loool. anaesthesia is now well known,) and particularly where the instruments are employed in dentistry, it is desirable to have an instrument in which the direction of the impinging atomized current'niny be changed, as, for instance,

from such disposition-of the tubes as will direct the currentagainst one jaw, to a disposition of the same tubes which will cause the. spray to be properly thrown against the opposite jaw, and the manner of constructing an instrument to produce such chang-e forms the subject of my present invention.

My invention consists in so applying the combined air and Huid-tubes to the vertical {luid-tube oileg that is placed in the .liquid-containing cup, that the position of said air and fluid-tubes, and theA consequent angle and direction of the atomizing points, may be reversed with reference to such Huid-leg.

The drawing represents an instrument embodying the invention, said instrument being one having a bifurcation at its atomizing-points to adapt it to the simultaneous freezing of the opposite sides of a jaw or other member of the bodyA thin enough to require or to *render it sometimes desirable to `i`reeze both surfaces, the invention being, however, equally applicable to instruments not having suclibifureatio'n, but having the -atomizing end of the tube be'ntror set at an angle to the main part of the 'tubes, for the purpose of giving to the current an upward ordownward or a lateral direction.

a denotes the air-tube, Z theiluid-tube, c the fork, al the atomizing points or jets, shown as curved in an upward direction. e is the fluid-leg, or the vertical. continuation of the fluid-tube b, which is placed' in the cupV or vessel containing the volatilel liquid to be atomize'd. Instead of making this leg integral with the main tube b, I attach it thereto by a joint, so that the tubes a and b may be connected to and disconnected therefrom, or

may be'reversed in position relatively thereto, to bring the atomizing end of the tubes into the reversed posi-- tion shown bythe red lines at A. This connection is shown as made by a screw-joint, the upper end of tho tube e having a screw-thread formed in it, which screws upon a; corresponding thread c ut on the outer surface oi' an arm or shank, f, extending from the tube b. On the upper side of the tubes a 'b is a similar tubular screwshank or extension,j", (the ltube in which connects with the tube a, as shown by the dotted line in blue,) and this shank is covered by a {luid-tight and air-tight screw-cap, g, the two screw-Shanks ff interchangeably fittingthe screw-thread 'in thetop of the leg e and that in the cap g, so that (as will be readily understood) by unscreiving the cap and the leg the pipes a b may be `reversed in position, as shown by thc red V1ines,`the screw-shank f' being the'nvconnected to the leg e and the shankfcovered by the cap g. The air pipea extends straight out to the nozzle li, by which it is connected to the air-supplying apparatus, air passing through the same, as denoted by the Adotted line in red, and to make a connection between the duid-leg and theshankf the' pipe I) extends through from one shank to the other, being made of bulb-form where it passes the pipe a, and chambered out between the pipes a' and b, the fluid passing from the leg to each shank, as shown by`the dotted lines in blue.

Instead of this specific construction, the contiguous tubes a and b may be attached to the tube e by a ground or a rubber or Velastic joint, so that the tubes by rotation upon such joint may be brought to the desired change of position; but for general use I prefer the construction shown, and consider it the most reliable and practical. I claim an ntomizing instrument, in which the contiguous air .and fluid tubes areA connected to the vertical or cup tnbe,'so as to be reversible with relation thereto, substantially as set forth.
